The following dates are fixed: latest date by which this document has to be implemented at national level by publication of an ide

16、ntical national standard or by endorsement (dop) 2016-01-05 latest date by which the national standards conflicting with this document have to be withdrawn (dow) 2018-01-05 This document is intended to be used in conjunction with EN 60335-1:2012 and its amendments. Attention is drawn to the possibil

17、ity that some of the elements of this document may be the subject of patent rights. CENELEC and/or CEN shall not be held responsible for identifying any or all such patent rights. This standard covers the Principle Elements of the Safety Objectives for Electrical Equipment Designed for Use within Ce

18、rtain Voltage Limits (LVD - 2006/95/EC). BS EN 50615:2015- 5 - EN 50615:2015 Introduction This European Standard has been prepared to provide a means of conforming to essential safety requirements of the Low Voltage Directive 2006/95/EC. Other requirements and other EU Directives may be applicable t

19、o the devices within the scope of this standard. This European Standard is a product family standard dealing with the safety of devices for fire prevention and suppression for hobs (cooktops). This European Standard recognizes the level of protection against fire hazards of stationary cooking ranges

20、, hobs and similar appliances. A device for fire prevention and suppression for hobs (cooktops) that complies with the text of this standard will not necessarily be considered to comply with the safety principles of the standard if, when examined and tested, it is found to have other features that i

21、mpair the level of safety covered by these requirements. This European Standard takes into account the requirements of the HD 384 Series as far as possible so that there is compatibility with the wiring rules when the device is connected to the supply mains. However, national wiring rules may differ

22、. This European Standard applies in conjunction with EN 60335-1:2012 and its amendments, which is referred to in this text as “Part 1”. This European Standard supplements or modifies the corresponding clauses of Part 1 as indicated in the text. Although from evidences available the main cause of pro

23、blems is fire, also production of dangerous amount of smoke or just smoke, that contains dangerous substances, was considered, but during the development of the standard it was not possible to develop a reproducible test for such detection. This subject is therefore under consideration. BS EN 50615:

24、2015EN 50615:2015 - 6 - 1 Scope The first sentence in the Scope of EN 60335-1 is replaced by: This European standard deals with the safety of electric devices used for detection, prevention and suppression of fire originated: from a cooking process, or from flammable material left on the hob. NOTE T

25、he provisions of this document, duly adapted to the specific installation and conditions of use, may be taken into consideration as guidance also for the protection from fire originated from the use of portable cooking appliances or from grills in the oven cavity. The devices covered by this Europea

26、n Standard may operate by interaction with, or integration of, other devices such as smoke detectors, fire detectors, motion detectors, CO detectors and fire extinguishers that are covered by their specific applicable standards. 2 Normative references The following documents, in whole or in part, ar

33、Addition: The tests shall be carried out in a test room having a volume between 20 m and 30 m. For the tests of 11.104.1 and 11.104.2, devices that only depend on ambient temperature for their operation shall be tested at an ambient temperature of 4005+C. Verification of the type of operation shall

34、be done by examination of the technical documentation delivered by the manufacturer. 6 Classification This clause of part 1 is applicable except as follows: 6.101 With reference to the type of intervention the devices shall be of one of the following categories: Category A, Category B, Category AB C

35、ompliance is checked by inspection and by the relevant tests. 7 Marking and instructions This clause of Part 1 is applicable except as follows. 7.1 Addition: Devices shall be marked with the reference to their category. 7.12 Addition: Instructions shall give information to the user with regard to th

36、e meaning/function of the marked category. In case the device is suitable only for given types of cooking appliances or for hobs with a maximum width this shall be stated in the instructions. BS EN 50615:2015EN 50615:2015 - 8 - Devices for fire prevention, detection and suppression will not detect a

37、ll possible hazards due to different cooking habits. Whenever relevant, the details on the interval for technical check and maintenance done by the manufacturer of the device or his authorized representatives shall be stated. Specific instructions for user maintenance (e.g. cleaning of the detection

38、 device, periodical verification of functionality, etc.) shall be given. For Category B devices: this device may not be suitable for fires originating from flammable materials left in proximity of the hob or on the hob For Category A devices: this device is not suitable to control fires originating

39、in an oven or in an oven grill. 7.12.1 Addition: Instructions shall state the specific installation conditions and, if relevant, the limitations of use (e.g. in case when no range hood is foreseen in the installation or in case of cooking appliances not installed against the walls of the kitchen or

40、the reference to the specific products for which the device is designed). 8 Protection against access to live parts This clause of Part 1 is applicable. 9 Starting of motor-operated appliances This clause of Part 1 is not applicable. 10 Power input and current This clause of Part 1 is applicable. 11

41、 Heating This clause of Part 1 is applicable except as follows. 11.1 Addition Compliance is checked with the tests in 11.104. 11.2 Addition: The devices shall be installed according to the instructions given by the manufacturer. If the instruction manual provides multiple ways or positions for insta

42、llation of the device(s) the device(s) shall be installed in the most unfavourable position. Based on the specific instructions given by the manufacturer, a hob having six hob elements as defined in EN 60335-2-31:2003, 11.2, is installed in a base cabinet having the following dimensions: BS EN 50615

43、:2015- 9 - EN 50615:2015 Width: 119,8 2 cm, Depth: 60,0 2 cm, Height: 86,0 cm 2 cm. One cabinet with dimensions Width: 59,8 cm 2 cm, Depth: 60,0 cm 2 cm, Height: 86,0 cm 2 cm is installed on both sides of the base cabinet supporting the hob. In case the manufacturer limits the use of the device to a

44、 hob having four elements, the hob as defined in EN 60335-2-31:2003, 11.2, is installed in a base cabinet having the following dimensions Width: 59,8 cm 2 cm, Depth: 60,0 cm 2 cm, Height: 86,0 cm 2 cm If the instructions for use foresee the use of a range hood, a cabinet with dimensions Width: 59,8

45、cm 2 cm, Depth: 37,0 cm 2 cm, Height: 70,0 cm 2 cm is installed on both sides of the range hood. If the device is foreseen to be installed with hobs with less than 4 or more than 6 hob elements, the hob indicated by the manufacturer of the device shall be used, choosing the one giving the most unfav

46、ourable results. The tests can also be performed with the suitable hobs specified in the instructions by the manufacturer choosing the one giving the most unfavourable results. If no specification is available in the instructions, then the hobs required by EN 60335-2-31 shall be used. If devices of

47、Category A, or Category B or Category AB are integrated in the range hood or in the hob, the range hood or the hob are subjected to the tests as delivered. In case of devices foreseen to be integrated or mounted on a specific model of range hood, the range hood foreseen by the manufacturer of the de

48、vice is installed in a cabinet having suitable dimensions. The test shall be carried out with the range hood operating on both conditions: switched-off and switched on at maximum air flow. The bottom level of the cabinets shall be at 55 cm 2 cm from the top of the base cabinet supporting the hob. A

49、typical installation for a 4 hob elements is given in Figure 101 Figure 101 Addition During this test there shall be no activation of the alarm. Add the following new sub clauses: BS EN 50615:2015EN 50615:2015 - 10 - 11.101 Verification of correct operation of devices for fire detection and suppression The device shall take measures to ensure that, as a result of unattended operation or excessive temperature, fires caused by the cooking process are avoided. For category A and AB devices, in addition, the risk of dangerou
